Abstract

The Gunungsewu area, Yogyakarta, Indonesia is known as a karst landform with unique hydrogeological setting. Water is stored and flown in subsurface chambers and channels. There are some underground rivers, with flow rate ranging from 200 l/sec to 1,000 l/sec, used by the local people to fulfil their fresh water needs. The Gunungsewu is often exploited as a research area by karst geologists, geomorphologists, and hydrogeologists due to its fascinating natural features. A variety of groundwater modelling has been developed, including mathematical modelling, but in this case, the water is generally illustrated as flowing through a pipe with simplified channel shape. In fact, the form of karst channels is actually uneven. This irregularity causes karst channels should be described as fractal geometry. Consequently, some groundwater flow mechanics equations need to be modified, so that they are more appropriate to be applied in the karst region.
